Adding a set of waypoints or marks in SeaNav

Here is how to import a list of Latitude and Longitude positions as a set of waypoints and route  into SeaNav.

Step 1. Create a spreadsheet with the Latitudes and Longitudes either in Degrees, Minutes, Seconds or Decimal degrees with a header line including latitude and longitude like so:-

One caveat – If your co-ordinates are West of the meridian like mine are you will need to enter them as negative values before dropping on the kml converter! Ditto south of the equator.

I use google docs to create the spreadsheet and then download it as a csv or excel spreadsheet to my desktop.

Step 2. Next use this excellent free online converter tool at http://www.mapsdata.co.uk/online-file-converter/

If you have entered the co-ordinates in decimal degrees then you can just drag and drop the xls/cvs  file you have just created and downloaded onto the kml converter tool:-

But if like me you use DD MM SS  (Degrees, Minutes, Seconds)  then you need to use their Convert DMS to decimal” tool first. Drag your xls/csv file onto it , edit the resulting csv file to change the existing DMS latitude and longitude fields to a different name, e.g. dmslatitude etc. and then drop the resulting file onto the KML Converter box above.

Step 3. Convert the kml to a kmz file. Simply compress/zip the resulting kml file and rename the extension from .zip to .kmz.

e.g. ClubMarks.kml -zip-> ClubMarks.kml.zip  -re-name-> ClubMarks.kmz

and then email the kmz to yourself so you can pick it up in email on your iPhone.

Open it in the iPhone email client. Here are screenshots of the final step of the import process:-

Open the email and tap the kmz icon.

SeaNav – Marine Charts & Nautical Navigation App for Mac OS X

The newest member of the SeaNav app family brings our acclaimed marine charts to Mac – letting you explore and plan your boating trips on your Mac, then export your route to your iPhone for navigation while at sea – or plug in a GPS unit, and navigate with your laptop and our hi-res vector charts. SeaNav for Mac US has the latest NOAA ENC Digital Vector Marine charts covering the whole of the USA and Great Lakes, SeaNav for Mac UK has the latest UKHO UK and Ireland vector charts. SeaNav for Mac is exclusively available on the Mac App Store.

  • Includes NOAA US Coastal, Great Lakes and USACE Inland Charts.
  • Buoys, lights etc. are tappable with bearing and distance.
  • Seamless fast panning and zooming across charts.
  • Route Planning and tracking with Waypoints, SOG, COG, ETA etc.
  • Charts work offline
  • Route export, import and sharing (KML, share via disk or Dropbox)
  • Live AIS Ship positions
  • Share routes and tracks with SeaNav on iPhone and iPad

SeaNav uses the latest Digital Vector charts providing a wealth of benefits and advantages over raster charts. Buoys, Lights, Bridges, Depth Contours, Depth Soundings, Rocks, Anchorage areas, NOAA Weather Buoys etc. are all selectable and have real time distance, bearing and detail information. Turn off layers to de-clutter the display and only show what is important at the time. Tides, moon and sun times and weather are also all available at your fingertips.

SeaNav Mac Sailing

SeaNav lets you measure distances and bearings and record waypoints on routes. When at sea, the app’s Sailing HUD shows your position, Course over ground (COG), Speed over ground (SOG), Vector Made Good (VMG), Estimated Time of Arrival (ETA), Distance and bearing to next Waypoint. Waypoint reached alerts, auto-routing to the next waypoint and collision alerts.

SeaNav is also available for iOS, so you can plan a route on your Mac and share the route with your iPhone or iPad – or take your iPhone sailing, then send your track back to your Mac.

Plug in your GPS unit and go – SeaNav works with Bluetooth and serial GPS units, and those which provide location or AIS service via TCP or UDP or TCP, including devices from Lowrance, Simrad and B&G GoFree. But GPS is only required for real time route navigation, you can plan routes without GPS then send them to your iPhone for use while at sea. SeaNav’s optional Real time AIS, Tides and Weather information require an active internet connection.

Your purchase of SeaNav includes 12 months free updates to the included US chart set.

SeaNav for Mac is exclusively available on the Mac App Store.

Navionics Boating (free US NOAA Charts) vs SeaNav

Navionics have  launched a new version (7.0) of their Navionics Boating app which now includes free US NOAA vector charts. If you are boating in the US you can now get a well respected and functional marine navigation app on your iPad and iPhone without spending a cent. What are they up to? Why should you go anywhere else? How can they give away a full blown marine navigation app for free? We hope the following comparison  and charts around San Francisco can help you decide which route to follow.

Here is the view of San Francisco from SeaNav within a 3 mile radius  – the horizon for most leisure boat users (6NM x 6NM square) :-

and the same scale on Navionics Boating with their free NOAA charts :-

What?

We zoomed in and eventually (at three times the scale) details appeared:-

 

Compare this with SeaNav at the same scale:-

We hope you will agree that its a lot less cluttered, has more relevant information and is a lot easier to view. Zoom in and more details and spot depths will be shown. You can also choose what level of detail to show in SeaNav.

Other key differences:-

  • SeaNav includes full live navigation features including COG, SOG, HDG, ETA, Waypoint distance and time, Cross Track error, Course and North up view etc. – it’s at least a $5 extra for Navionics and that doesn’t get you much of what SeaNav offers.

  • SeaNav includes Tides – Navionics Boating free doesn’t – you have to buy their  USA chart set  at $70.

  • SeaNav has a unique and highly recommended AR Camera view showing buoys, ships, landmarks  etc. overlaid on the real time camera view.

  • SeaNav has free support for the amazing fully waterproof Pebble SmartWatch – forget a $500 Garmin Quatix!

  • SeaNav has live AIS Ship data overlay including collision detection. (via Boat Beacon).

  • SeaNav – buy once  and runs at full HD on both your iPad and iPhone with no need to purchase another version.

  • SeaNav including full charts is just $19.99 in the US and £14.99 in the UK. See how this unfortunate user ended up paying over £70 ($100) for Navionics “Free”:-

And, SeaNav iPhone and iPad is now available for you to try for free. Click here to learn more.
